Title: Web Accumulators
IPC: B21C49/00
Filed: 1979-05-30
Abstract: An accumulator suitable for a strip processing line comprises a strip- supporting trolley 8 for the drum 12 of a loop type accumulator, which trolley moves substantially horizontally between a minimum strip accommodation position and a maximum strip accommodation position, at least one intermediate strip support station being provided adjacent the path of the trolley. The, or each, station comprises a pivotable member with a pair of projections, e.g. arms 72, 74, one of which carries a strip support member e.g. a roller 4. The projections are arranged so that trolley travel towards the maximum accommodation position causes the second projection 72 to pivot the support member into a strip- supporting position, while trolley travel towards the minimum accommodation position causes the first projection 74 to pivot the support member into an inoperative position. <IMAGE>

Title: Pneumatic conveyor seals
IPC: F16J15/40
Filed: 1980-01-22
Abstract: An annular seal 1 for engaging the inner surface of a tube or cylindrical bore 3, so as to inhibit fluid leakage past a piston or other body in the tube, has a deflector ring 4 spaced from it which acts to divert fluid which would otherwise leak past the seal during relative lateral movement between the seal and the tube particularly when sealing is impaired by the effect of tube irregularities or piston wobble.

Title: Determination of moisture content
IPC: G01N33/02
Filed: 1980-06-10
Abstract: In a method of measuring the amount of moisture or water in materials, in particular foods, the material is subjected to the action of a liquiform, organic, hydrophilic water extraction agent and the water content of the extract is determined by mixing the extract and a colour reagent consisting of a transitional metal salt whose metal ion in the presence of anions and the solvent in the extract absorbs a first wavelength of electromagnetic radiation and in the presence of water in addition absorbs a second wavelength of electromagnetic radiation. A decrease in solvent concentration in relation to the anion concentration brings about reduced absorption of the first wavelength. A sample of the reagent- treated extract at a predetermined, substantially constant temperature is transilluminated with electromagnetic radiation of the first wavelength, and an optical characteristic of the sample is measured and related to predetermined data which correlate different water contents in the extraction agent with said optical characteristic. The transitional metal salt may be a cobalt salt, and the first wavelength may be 655 nm. Extracts of chloride-containing sample materials are preferably saturated with chloride before measurement of the optical property or magnitude.

Patent GB-2089992-A (GB)
Title: Target Depth Reading Metal Detector
IPC: G01V3/10
Filed: 1981-11-09
Abstract: A buried metal detector of the transmit-receive type includes a non- linear amplifier for producing a modified output signal whose amplitude is related to the depth that the detected metal object is buried below the transmit coil (10). A synchronous demodulator means (20) multiplies the receive coil (12) signal by a phase shifted reference signal (22) to eliminate mineral soil signal components from its demodulated output signal. The demodulated output signal is applied to the input of the non-linear amplifier (28) which compresses the signal amplitude variations of the demodulated output signals produced by metal objects buried at different depths. Amplifier (28) is preferably a logarithmic converter amplifier whose output signal amplitude is linearly related to target depth over a predetermined range of distance. The modified output signal is applied to a depth indicator means (30). The detector may also discriminate between different types of metal objects by the polarity of a discriminate demodulator (34) output signal which is combined with an audio oscillator (50) signal to provide a modulated output signal that is applied to an audible indicator means, such as a loud speaker (38), to indicate only desired metal objects. <IMAGE>
